To all whom it may concern Be it known that l", JOSEPH E. Coonnan, a

citizen of the United States, residing at Elkhart in the county ofElkhart and State of tent afforded without increasing the diameter, thusgiving ample room for the computations while avoiding a structure that1s bulky and unwieldy. Users of this class of scales demand that notonly shall the com- 1 puted an'iount be presented clearly and inposition convenient for reading; at the users side of the scale but thatthe purchaser shall also be able to readily observe the indicatedWeight. This makes it necessary to employ a weight dial in addition tothe conical computing dial, since the latter is not in position to beobserved from the customers side.

The conical dial, however, must rotate inorder to bring the matter onthe under side to the top where it may be read, but a rotatmg Weightdial for the customers side is undesirable because of the fact that theaver-- age customer has been so long accustomed to the fixed dial androtating pointer that the reverse arrangement loads to incredulity andrequires explanation on the part of the salesman to convince thecustomer-o1 the accuracy of the mechanism.

objections, and therefore has for its primary ob ect to provide a scalewhich employs both the computing conical dial and the fixed Weight dialand which at the same time is simple, compact and of the pcndulum-woightand beam tygc with the minimum number of motion-transmlssion devices.

lNith a view to the attainment. of those ends and the accomplishmcnt ofcertain other objects which will hereinafter appear. the inventionconsists in the features oi. novelty in the construction. combinationand arrangement of parts which will now be dcscribcd with reference tothe accompanying drawings, and then more particularly poinl'cd out inthe claims.

l l l l l y l l l In the said drawiugsl igure 1 is a rear elevation,partly in vertical longitudinal section, of a Weighing scaleccmstru'cted accord ing' to this invention. Fig. 2 is a detail rearelevation of the conical dial casing; and Fig. 3 is an end elevation,with the-casing and some of the parts in vertical section, the plane ofthe section passing; throrg h the (L of the dial. Fig. l is a detailsectional view on line 4% of Fig. 3.

l is the conic: l computing diah-and 2 is the fixed weight dial beforereferred to. The latter is arranged as usual in a vertical plane, whilethe conical dial is mounted to rotate on a horizontal axis, and to thatend is provided with a horizontal shaft 3. which supports and rotatesthe dial 1 at one end and carries at its other end a pointer or index 4in appromiatc position for reading with reference tolhc fixed Weightdial 2. The index 4 is sccurcd to the shaft 3 in any suitable way. whilethe cone 2 is mounted upon the shall by moans of a hub 5 at the apex ofthe cone, and a spider or plurality of spokes 3 at the base of the cone.These spokes are shown as bciug formed up\ out of sheet-metal for thesake of lightness, which may be ribbed or corrugated longitudinally ofthe spokes for the sake of rigidity. and their outer cnds may be formedintegrally with a rim or ring 7. which is also ribbed as shown at 8 togiro it llio'rmpiisitc st-ifiucss. The ring I is situatcd directly at orclose to .the base of the cone. but the spokes ll are preferably cantedor carried inwardly at their contiguous cnds in order that other partsof the mcchanism or structure as will bc presently dcscribcd may bclocated within thc space bclwccn the base and apex of the My inventionis designed to avoid these cone and thereby considerably reduce thewidth of the scale as well as shorten thc length of the shaft 3, andmaking it possible to employ a lighter shaft and without the necessityof providing it with an intermediate bearing to resist the vibrationlikely to be occasioned by the operation of the dcyiccs whichimpartrolalion to the cone. 'lhc spokes or spidcrs (3 being ofshcct-mctal. it is desirable to supply their inner ends with a hub S) ofmore substantial body to provide for thci' altachmcutlo the shaft Thishub is shown as being); formed with a flange 10. which is riveted orotherwise secured to the central part of thespider into which the spokesare merged. The apex of the cone is provided with an inwardly cuppedportion ll riveted or otherwise secured to the hub through which the endof the shaft projects, and the protruding end of the shatt is mounted ina suitable anti-triction bearing 1:2, mounted in the upwardly extendingend 13 of an arm 1 k and inclosed by the cupped portion ll of anexternal cap 15 secured to the portion 1.3 by a screw 16 or othersuitable means. The arm 14; is inclined so as to be parallel with theface of the cone and its inner end is provided with suitable means ofattachment such as screws 17, to a ring 18 situated in a vertical planeat the base of the cone. This ring is secured throughout a substantialportion of its lower side to a crescentshaped member 1.) of the mainbase frame oi the scale. The arm 14: is also braced and reinforced byone or more additional arms 20, 21 secured by screws 23 or othersuitable devices to the ring 18.

Rising from the upper edge of thecrescent shaped men'iber 19 is astandard 2?, which is inclined inwardly toward the hub t),'while itsupper end is between the plane of the base and the apex of the cone, andrising; from a similar crescent shaped member 24- on the opposite sideof the main frame is a standard 25, and in these two standards ismounted the knife edge pivot 26 of the pendulum weight 27, the latterbeing ad justably secured to a stem or arm hav ing a hub 29 formed on orsecured to the knife edge bearing, all as usual in the pendulum typescale. To oncside of the arm 28 is arranged a convolute cam 30 securedto or formed on the hub or otherwise suitably attached to the knife edgebearing 26, the cam being preferably situated between the standard 23and the arm 28; and ar ranged directly under the cam and in a planeparallel therewith and alst) in. a plane parallel with the base (it thecone. is the main scale beam 31, which is attached to the cone by aribbon 'or strip 32 in the usual or any suitable way the opposite end ofthe beam being provided with the usual knil'e edge bearii'ig S t havingpivot upon the main Prairie. l /hen these parts are in their normalposition or with the scale unloadcd, the pendulum weight 27 and its arm3.8 hang vertically andcross the beam 231 at some distance from its endwhere the titling or attaclunciu; 35 necessary tor its :ouncctiou to theribbon L is arranged. and' when the scale is loaded the pendulum arm andweight. swing f om this position in a pl: ne parallel with the plane ofthe base ol, the cone and the planeot the beams oscillation in a. di-'rection toward the pivot cud ol' the bcam where the casino has ampleroom to permit of this rising and Falling niolion without lliw neces ityl'or elongating. thc casing" bcyond dimensions otherwise rcipiired. it;-will also be seen that the small adjusting weight tit; and itssupporting arm ilT which connects the weight to the hub 29, are situatedand oscillate in a plane parallel with the base The end of the shaft 3opposite that sup ported by the bearing 12 is arranged'in a suitablebearing 36, supported on the upper end of a standard 37 formedwon theside frame Q-t continuous to the standard 25 and preferably in the sameplane as the standard 25, so as not to increase the width of the machinein a. direction lengthwise of the shaft. It will also be seen that thespace between the dials is considerably reduced by carrying the adjacentends of the spokes (3 inwardly so as to permit the standard 23 to beextended inwardly at its upper end a like extent.

The main base *lrame 19 is extended horizonlally lengthwise of the l am31 and in a direction parallel with the plane ol. the base of theconical dial, asshown in Fig. l, a sullicicnt distance to accommodatethe beam and the pan or platt'orm 38.
